FIELD

This application generally relates to automatically generating playlists for a user. In particular, the application relates to platforms and techniques for automatically generating playlists within a music service.

BACKGROUND

Music services are gaining in popularity as more consumers seek immediate access to comprehensive music libraries. For example, instead of purchasing individual copies of songs or albums (e.g., CDs), consumers can register with various music services to access music offered by the music services. Particularly, various music services and platforms enable users to download or stream specific songs, albums, or playlists to desktop applications or mobile devices. One benefit advertised by many music services is the ability to access music libraries where ever the user is located, so long as a network connection is available. However, there are deficiencies in existing music services and platforms.

For example, if the network connection falters or halts altogether, any music playing through the music service stops, and the music service's music libraries become inaccessible. This can be especially frustrating when the user will be without a network connection for an extended period of time, such as, for example, while travelling in a plane, working in a hospital or laboratory, or located at any other place with poor reception or a complete lack of connectivity. While some music services allow users to download music to the user's device and thereby, access the music independent of a network connection, this feature is useful only to the extent that the user remembers to download the music before the network connection is severed.

In accordance with one or more principles of the invention, systems and methods are provided for automatically generating a playlist while connected to a music service and providing access to the automatically-generated playlist when the music service is unavailable, the automatically-generated playlist including music files that were accessed through the music service and are temporarily stored in a local memory of the device. According to embodiments, an electronic device in combination with a music service server can implement the systems and methods that generate the playlists and provide access thereto. In embodiments, a user may access the music service through a music service application operating on the electronic device. According to aspects, the music service application may be configured to automatically cache, or temporarily download into a local memory, one or more music objects accessed using the music service, for example, via a streaming feature of the service. In embodiments, the music service application can automatically generate a playlist comprising one or more of the cached music files and store the playlist in the local or cache memory with a designation for “offline” access (e.g., when network communication with the music service server is not available). In this manner, the user can continue to have access to music, even if the music service application loses connection to the music service server, and even if the user does not actively download music to the device.

As used herein, a “music service” can be understood to be any service, platform, application, or the like that enables a set of users to access and manage media data, such as, e.g., media objects or music objects, among other functionalities. Further, as used herein, a “playlist” can be understood to be a listing, indication, or aggregation of one or more songs, tracks, albums, and/or other media data files or objects that are accessible to and manageable by one or more users, and from which the one or more users can select one or more songs for playback. In some cases, the media data files can be accessible locally to the device from which the user is accessing the playlist. In other cases, the media data files can be accessible via streaming from a remote server or from other devices connected to the device via a network. According to present embodiments, the music service enables users to share music with each other. In some embodiments, the set of users can register with the music service.

It should be understood that any music object sharing, identifying, determining, locating, retrieving, providing or the like can be facilitated by an electronic device singularly, or by the electronic device in communication with a server, such as a music service server. For example, the electronic device (e.g., smartphone, tablet computer, notebook computer, etc.) can request a server to locate one or more songs. Further, the server can provide any located songs to the electronic device for playback by a user. Further, both the electronic device and the server can execute a music service or similar music service module or application to implement the functionalities as discussed herein.

FIG. 1 depicts an environment 100 comprising components and entities of the embodiments as discussed herein.

The music service server 115 can comprise a combination of hardware or software components (such as a music service module 116), or combinations thereof, configured to support the facilitation of a music service, as well as the techniques for determining personal preferences as described herein. In some embodiments, the user 106 of the device 105 can register for an account or a registration with an associated music service and the music service server 115 and components thereof can provide music data or objects to the device 105 in accordance with a subscription of the user 106. For example, in some cases, the user 106 can select to download songs, tracks, and/or other music objects from the music service server 115 to the device 105. In other cases, the music service server 115 can stream songs, tracks, playlist files including songs, and/or other music objects to the device 105 for access and consumption by the user 106.

In embodiments as shown, the music service server 115 can couple to storage 117 that can be configured to store data associated with the music service server 115. For example, the storage 117 can store any associated music data as well as data related to subscriptions and other account information for users of the music service server 115. The device 105 can connect to the music service server 115 via a network 122 such as, for example, a wide area network (WAN), a local area network (LAN), or other networks. The network 122 can facilitate any type of wireless data communication via any wireless communication standard or technology (e.g., GSM, CDMA, TDMA, WCDMA, EDGE, OFDM, GPRS. EV-DO, WiMAX, WiFi, Bluetooth, UWB, and others). More particularly, the device 105 can send data to and receive data from the music service server 115 via the network 122. For example, the music service server 115 can receive music data requests from the device 105 and can transmit or stream music data to the device 105 according to the requests.

As shown in FIG. 1 , the environment 100 can further comprise a set of additional devices 110 that can also be configured to connect to the music service server ) 15 via the network 122. Each of the set of additional devices 110 can be associated with a set of additional users of the music service implemented by the music service server 115. More particularly, each of the set of additional users can have an associated account with the music service or can otherwise register with the music service. In embodiments, the device 105 can be configured to connect to and/or exchange data with the set of additional devices 110 via the network 122. Any of the additional devices 110 can send music data to the device 105 and/or to any of the remaining additional devices 110 via the network 122.

According to implementations, the music service server 115, the device 105, and the set of additional devices 110, and components thereof, can facilitate the management of music subscriptions of the users of the respective devices 105, 110. More particularly, the music service server 115 (and the music service module 116 thereof), the device 105 (and the music service application 107 thereof), and/or the set of additional devices 110 can enable the respective users to share music objects with each other. It should be appreciated that the music objects, as described herein, can be any type of music data and information such as, but not limited to one or more songs, one or more albums, a group of songs by a particular artist, one or more playlists, one or more music videos, various music artwork, and/or other types of media of data.

Users of the device 105 and/or the set of additional devices 110 can interface with respective devices 105, 110 to initiate a music service or application and manage the functionalities of the music service. The device 105 and/or the set of additional devices 110 can communicate with the music service server 115 to transmit share activity, identify music objects based on the share activity, and access the music objects. In embodiments, a user can select to play a music object, at which point the music service server 115 can retrieve the appropriate music object from the storage 117 and provide (e.g., by streaming) the music objects to the appropriate device 105, 110. In some embodiments, one or more of the music objects can be played from a local memory (e.g., local cache, disk cache, system cache, etc.) of the appropriate device 105, 110. In further embodiments, one or more of the music objects can be retrieved via a peer-to-peer (P2P) network among the device 105 and the set of additional devices 110.

According to embodiments, the user 106 can be “connected” to or “following” other users (such as users of the additional devices 110) via a social feature of the music service. In some cases, some of the “connections” can be mutual whereby if User A is connected to User B. then User B is connected to User A. In other cases, some of the connections can be one-directional whereby if User A is following User B, then User B is not necessarily following User A. The social feature can enable users to share music objects with additional users of the music service, such as a particular user sharing a music object with one or more connections or followers. In embodiments, one or more users can belong to a certain group or other type of aggregation of users. It should be appreciated that other types of connections, followings, and groups among users are envisioned. According to aspects, the social feature of the music service enables users to effectively and efficiently share music and other media with other users and groups of users.

According to embodiments, each user of the music service can have an associated music profile that can include any data related to the musical tastes, preferences, listening history, interactions or social network connections with artists and/or other users, listening data or trends, songs or artists that share similarities with other songs or artists that the user enjoys, has listened to, and/or is otherwise associated with the user, and/or any other data that can indicate the songs, bands, artists, genres, and/or musical eras that a user tends to enjoy or not enjoy. In embodiments, the music profile of the user can be based on other users, entities, or music or playlist curators that the user is connected to, “follows,” subscribes to, or is otherwise associated with in the music service. In some embodiments, the music profile may include a preferred list (also referred to herein as “favorites list”) that identifies each song, album, artist, playlist or other music object for which the user has indicated a preference. For example, in embodiments, the user may indicate a song preference by selecting a preferred option (e.g., “love it,” “like it,” “favorite,” etc.) associated with the song via a user interface associated with the music service application (such as, e.g., “love it” option 815 shown in FIG. 9 ).

In some embodiments, the music service application and or the electronic device can be operable in one of an “online mode” and an “offline mode.” The online mode may be initiated when network communication with the music service and/or the music service server is available. Conversely, the offline mode may be initialed when network communication with the music service and/or music service server is unavailable. In some embodiments, the online mode and/or offline mode are automatically selected by the music service application and/or the electronic device, depending on a status of the network connection. In other embodiments, a user may select between the online mode and the offline mode using a graphical user interface associated with the music service application (e.g., as shown in FIGS. 3 and 4 ). In some cases, the user may select the offline mode even though a network connection is available, for example, in order to avoid cellular data usage or limit the user's listening options to the music content specifically available offline.

In embodiments, the music service application may present different options, content, and/or functionality depending on whether the application is operating in the online mode or the offline mode. For example, the music service application may include an online version of the application that provides full access to the music service and the application's functionality (e.g., create playlists, browse music libraries, access featured playlists, albums, artists, and other music content provided by the music service, etc.). In embodiments, the online version may be a default version of the application and/or may appear whenever the application is in the online mode. In addition, the music service application may include an offline version that appears when the application is in the offline mode. In embodiments, the offline version of the application may provide access to songs, albums, playlists, and other music content that the user previously downloaded to the local memory of the device or otherwise marked for offline access. According to preferred embodiments, the offline version provides access to playlists that were automatically generated by the music service application and/or the device for offline access, as described herein. As will be appreciated, the offline version of the application may not provide content or functionality that requires network communication with the music service. In embodiments, when the music service application returns back to the online mode the online version of the application also reappears.

In embodiments, the music service and/or the music service application may include one or more aspects for facilitating the automatic generation of playlists comprising music objects cached in the local memory of the device 105 and for enabling access to the automatically generated playlists during the offline mode of the music service application. As used herein, the term “local memory” may refer to any type of memory that is capable of being used for temporary data storage, including, for example, a local cache, a system cache, a disk cache, a random access memory (RAM), or a cache memory. In some embodiments, the device 105, 110 may store different categories of data in separate memory locations. For example, music objects that are downloaded from the music service, or otherwise designated for offline access, by the user may be stored in one memory (e.g., an offline cache), and music objects that are automatically downloaded or cached by the device 104, 110 may be stored in a second memory (e.g., a system cache). In embodiments, music objects may be cached or temporarily downloaded to the local memory for a number of reasons, including, for example, conserving bandwidth by keeping frequently played songs readily -available, decreasing downtime or “dead air” between the end of one song and the beginning of the next song, or any other reason known in the art for caching music files during access to a streaming music service.

FIG. 2 depicts a sequence 200 of interactions between a user 202 of a music service such as, e.g., the user 106 discussed with respect to FIG. 1 ), an electronic device 204 (such as, e.g., the device 105 discussed with respect to FIG. 1 ), and/or a server 206 (such as, e.g., the music service server 115 discussed with respect to FIG. 1 ) in accordance with embodiments. In some embodiments, the sequence 200 may be associated with a method for automatically generating playlists that can be available for offline access. For example, the electronic device 204 and/or the server 206 may implement the functionalities depicted and described herein by executing an application on the device 204 and/or the server 206. In some embodiments, the device 204 may implement relevant portions of the sequence 200 may executing the all application and Interfacing with the server 206. In embodiments, the application may be the music service application or a portion thereof, such as an automatic playlist generation aspect of the application. In embodiments, the application may be a computer program stored on a non-transitory computer readable medium that is executable by a processor of the device. The device 204 and the server 206 may be communicatively coupled via a network connection (e.g., an Internet connection). The user 202 may interact with the device 204 through a user interface (e.g., a touchscreen) of the device 204. Although FIG. 2 is described with respect to playing music files or songs, it should be appreciated that other types of music objects (e.g., playlists, albums, artists, etc.) can be similarly involved in the sequence 200.

As illustrated, the sequence 200 includes the user 202 entering a request to initiate an. online mode (208) of the music service via the user interlace of the electronic device 204. in response to the online request 208, the device 204 communicates with the server 206 to Main access to the music service and thereby, initiates the online mode (210). In some cases, the online request 208 may be sent automatically in response to the user 202 logging into the music service and/or the music service application on the device 204. In other cases, the online request 208 may be sent in response to a manual input entered by the user 202, such as, e.g., selecting a “go online” option via the user interface (e.g., by turning off an offline mode option 405 in FIG. 5 ).

Once connected to the music service in the online mode, the user 202 can browse and select music files from the music service via the user interface of the device 204 and playback selected music files via a speaker of the device 204. When streaming a selected music file from the music service server 206, the music file may be cached simultaneously with, or at least partially overlapping, playback of the selected file. For example, upon receiving a request to play a selected music file, the device 204 may begin downloading the requested music file from the server 206 and playing the downloaded portion of the file via the speaker. Typically (e.g., if the network connection is sufficiently fast), the device 204 can download the music file in its entirety before playback is complete. While playback catches up, the device 204 can cache the downloaded portion of the music file in the local memory of the device 204 (e.g., the local cache or system cache). In embodiments, the device 204 may cache incoming music files to provide faster access to requested data. For example, if a given music file was previously cached, the next time the file is requested, device 204 can access the music file directly from the local memory, rather than requesting the file from the server 206.

In embodiments, the stored music files may be removed or deleted from the local memory at regular time intervals, upon reaching a storage capacity of the local memory, after playback has completed, or at any other time specified by a cache management plan for the music service application and/or the device 204. For example, in some embodiments, a preset amount of the local memory may be allocated or designated for caching music files (e.g., two gigabytes (GB), one GB, etc.). In other embodiments, a dynamic amount of the local memory may be allocated, for example, by designating a percentage of the available storage capacity for caching music files (e.g., ten percent, twenty percent, etc.). As another example, in embodiments, each music file may be assigned a timestamp upon caching the music file, and music files having a timestamp older than a threshold date and/or time can be automatically deleted or removed from the local memory. In yet another example, cached music files for which the user indicates a dislike or negative preference (e.g., selection of “hate it” option 816 in FIG. 9 ) may be automatically removed front the local memory.

In some embodiments, the music service application may pre-cache music files in anticipation of the next request, for example, by downloading, and storing in the local memory, songs that are expected to be played next. For example, when the user begins playing a song from within an album or playlist, the music service application may begin pre-caching a preset portion of the album or playlist, such as, for example, a number of sequentially occurring songs (e.g., the next three or four songs), an amount of sequential playback lime (e.g., the next twenty or thirty minutes of playback), or an amount of sequentially-organized data (e.g., the next 500 megabytes (MB)). In some embodiments, pre-cached music files may be automatically deleted from the local memory if the user indicates a lack of interest in the files and/or the associated album or playlist, for example, by switching to a different album or playlist.

In embodiments, while in the online mode, the device 204 may communicate with the server 206 in order to report information related to songs accessed using the device 204, such as, for example, listening history (e.g., whether the user completed playback of the song or skipped to another song, the number of limes the user has requested playback of that song, etc.), preference information (e.g., whether the user indicated a preference or a dislike for the song), and social interaction information (e.g., whether the user shared the song with other users on the music service). The music service may add this song information to the user's music profile, which may be stored at the server 206.

Referring back to the sequence 200 in FIG. 2 , in some embodiments, the device 204 can identify (216) whether music files accessed by the user 202 satisfy a pre-designated condition associated with the music service application's feature of automatically generating playlists available for offline access. In other embodiments, the server 206 may perform the identifying (218) and transmit the identification of the music file to the device 204. In some embodiments, the identification 216/218 only involves music files that are already stored in the local memory of the device 204. For example, the device 204 and/or the server 206 may identify which of the currently-cached music files satisfy the pre-designated condition. In other embodiments, the identification 216/218 can involve any music file accessed by the user through the music service.

In embodiments, the pre-designated condition includes receipt of a user preference for. and/or a user selection of, a given song, album, playlist, or other music object. For example, the pre-designated condition may include receipt of at least one of: an indication from the user to playback the music file, a playback request for the music file within a recent time period (e.g., in the past twenty-hour hours, in the past week, etc.), an indication to add the music file to the user's preferred list, an indication with the recent time period to add the music file to the user's preferred list, a threshold number of playback requests for the music file, or a threshold number of playback requests for the music file within the recent time period. In some embodiments, the music service application may be configured to identify (216) music files that satisfy at least one of a plurality of pre-designated conditions. In other embodiments, the music service application may be designed for identification (216) based on one pre-designated condition, such as, e.g., receipt of a playback request within the recent time period.

In embodiments, the device 204 and/or the server 206 may automatically identify music files meeting the pre-designated condition at predetermined time intervals, in response to each playback request, preference indication, or other action by the user, or based on a variety of other factors. For example, the device 204 and/or the server 206 may search every two minutes for music files satisfying the pre-determined condition. As another example, the device 204 and/or the server 206 may identify each music file played by the user as satisfying the pre-designated condition. In some embodiments, the device 204 and/or the server 206 may also identify music files that no longer meet the pre-designated condition. For example, a music file that has not been played within the recent time period may be deleted from the local memory and consequently, removed from the list of identified music files.

Referring back to the sequence 200 shown in FIG. 2 , in embodiments, the device 204 can automatically add (224) the identified music files to an automatically-generated playlist stored in the local memory of the device 204. The automatically-generated playlist may become accessible when the music service application is in the offline mode, for example, through the offline version of the application. In embodiments, the automatically-generated playlist can be “dynamic,” since the contents of the playlist may be continuously updated as music files are added, or removed from, the local memory. For example, any new music files identified (216/218) as satisfying the pre-designated condition may be automatically added to the playlist. As another example, music files that no longer satisfy the pre-designated condition may be automatically removed from the playlist. In some embodiments, music files may also be removed from the playlist upon reaching a preset content limit, such as, e.g., a preset number of songs (e.g., twenty songs, twenty-five songs, etc.), a preset amount of play time (e.g., twenty minutes, thirty minutes, etc.), and/or a preset amount of disk space (e.g., two gigabytes (GB)). In some embodiments, the preset content limit may be defined by an available storage capacity of the local memory.

In some embodiments, the identified music files are previously-cached files stored in the local memory (e.g., where the identified files are songs that have been played within a recent time period). In other embodiments, the identified music files may be downloaded to the local memory from the music service server 206 prior to adding the files to the playlist (e.g., as described with respected to FIG. 11 ). For example, in some cases, the identified files may be songs for which the user has indicated a preference but are no longer stored in the local memory (e.g., because the files have not been played within the recent time period). In such cases, in response to the identification 216/218, the identified music files may be downloaded to the local memory and then added to the automatically-generated playlist.

Referring back to the sequence 200, in embodiments, the user can request (226) to initiate the offline mode of the music service application via the user interface of the device 204 (e.g., by selecting the on position of offline mode option 305 in FIG. 4 ). In response to the offline request 226, the device 204 can enable (228) access to the automatically-generated playlist, as well as any other features associated with the offline version of the music service application (e.g., turn off any network-related functions, present music content available for offline access, etc.). For example, upon initiating the offline mode, the music service application may present the automatically-generated playlist to the user and display an option to initiate playback of the stored playlist (e.g., play option 511 in FIG. 6 ). In embodiments, the user 202 can request (230) to play a music file included in the automatically-generated playlist using the user interface of the device 204. In response to the playback request 230, the device 204 can initiate (232) playback of the requested music file from the local memory. Alternatively, the user 202 can request to play the entire playlist, through the user interface, and in response, the device 204 can initiate playback of a first song include in the playlist.

FIGS. 3-9 illustrate exemplary interfaces associated with the execution, facilitation, and implementation of an aspect of the music service designed to automatically store, in a temporary memory of a user device, a playlist comprising cached music objects accessed by the user during an online mode of the music service, the stored playlist being made accessible during an offline mode of the music service. More particularly, FIGS. 3-9 illustrate screenshots of exemplary graphical user interfaces associated with a cached playlist generation aspect of the music service application executing on an electronic device. The exemplary interfaces can be displayed on displays of devices of the users of the music service, such as the device 105 and the additional devices 110. The devices can be configured to execute the music service application, and the interfaces of the music service application enable the users to provide input associated with various functionalities. The data associated with the exemplary interfaces can be transmitted to, received from, and/or synchronized with a server, such as the music service server 115.

The users can interface with the music service application via a user interface of the devices, such as a touchscreen 301, as illustrated in FIG. 3 . The exemplary interfaces can be displayed on the touchscreen 301, which includes contact-sensing technology configured to sense or detect user contact on the touchscreen 301 and to send one or more signals indicating detection of a contact-based input to a processor (e.g., processor 1014 in FIG. 10 ) executing the music service application, it should be appreciated that the interfaces of FIGS. 3-9 are merely exemplary and can comprise other various details, arrangements, and/or selectable options.

FIG. 3 depicts a screenshot of an exemplary settings interface 300 associated with the music service application. The interface 300 can appear upon selecting a settings option (e.g., settings option 403 in FIG. 5 ). In FIG. 3 , the settings interface 300 is being accessed while the music service application is operating in the online mode, e.g., in the online version of the application.

FIG. 11 is a flowchart of a method 1100 for an electronic device (such as the device 105) to automatically generate a playlist comprising cached music files accessed by a user of a music service. It should be appreciated that the functionalities of the method 1100 can be implemented with the electronic device executing an application and interfacing with a remote server, such as the music service server 115. In embodiments, the application may be the music service application or a portion thereof, such as an automatic playlist generation aspect of the application. In some embodiments, the application may be a computer program stored on a non-transitory computer readable medium that is executable by a processor of the device. Further, according to embodiments, the electronic device includes a display, a user interface (such as the touchscreen 204), a memory (such as the memory 1016), and a processor (such as the processor 1014) communicatively coupled to the display, the user interface, and the memory.

The method 1100 can begin at step 1102 where the processor determines whether an indication to initiate an online mode of the music service application has been received. In embodiments, during the online mode, the device is communicatively coupled to a server affiliated with the music service. If the answer at step 1102 is “no,” the method 1100 loops back to step 1102 and waits for the indication to be received. If the answer at step 1102 is “yes,” the method 1100 continues to step 1104, w here the online mode of the music service application is initiated. At step 1106, the processor determines whether at least one media object accessed by the user through the music service satisfies a pre-designated condition, the at least one media object being included in a plurality of media objects accessible via the music service. In embodiments, the at least one media object includes at least one of a music file, an album, or a playlist. If the answer at step 1106 is “no,” the method 1100 continues to step 1108.

If the answer at step 1106 is “yes,” the method 1100 continues to step 1110, where the processor identifies the at least one media object as satisfying the pro-designated condition. In some embodiments, the pro-designated condition includes receipt of a playback indication, from a user of the music service, to playback the at least one media object. In one such embodiment, the playback indication may be received within a predetermined time period prior to the identification of the at least one media object, as described herein. In other embodiments, the pre-designated condition includes receipt of an indication, from a user of the music service, to add the at least one media object to a preferred list associated with the user on the music service. In one such embodiment, the preferred indication is received within a predetermined lime period prior to the identification of the at least one media object, as described herein. In still other embodiments, the pre-designated condition includes a threshold number of playback requests received in association with the at least one media objet within a predetermined time period, as described herein.

In some embodiments, the method 1100 includes step 1112, where the processor caches or temporarily stores the at least one media object identified at step 1110 in the memory of the device. For example, the step 1112 may be needed if the at least one media object identified at step 1110 is not stored in the memory of the device, specifically in a cache memory of the device. If, on the other hand, the identified media object has already been cached by the processor, the method 1100 will continue from step 1110 to step 1114.

At step 1114, in response to the identification at step 1110, the processor automatically adds the identified media object to a playlist stored in the memory of the device. In embodiments, the playlist includes one or more additional media objects that satisfy the pre-designated condition and arc cached in the local memory of the device. In some embodiments, the playlist includes each media object that satisfied the pre-designated condition during a predetermined time period (e.g., within the last week, the last month, etc.)

In some embodiments, the method 1100 includes step 1108, where the processor determines whether a predetermined threshold has been reached for a media object included in the stored playlist. If the answer is “yes,” the method 1100 continues to step 1116, where the media object is removed from the stored playlist, if the answer is “no” at step 1108, the method 1100 continues directly to step 1118. In some embodiments, the predetermined threshold is defined by a storage capacity of the memory (e.g., whether a maximum disk space, or a percentage of the available disk space, has been exceeded). In other embodiments, the predetermined threshold is related to a timestamp assigned to the one or more media objects (e.g., whether the timestamp is older than a predetermined time). In some cases, media objects may be removed from the playlist in order of increasing playtime, so that the least played music objects are deleted first. From step 1116, the method 1100 continues to step 1118.

At step 1118, the processor determines whether an indication to initiate an offline mode of the music service application has been received via the user interface of the device. In embodiments, during the offline mode, the device is not communicatively coupled to the server. If the answer at step 1118 is “no,” the method 1100 continues back to step 1106 to check whether another media object has been identified. If the answer at step 1118 is “yes,” the method 1100 continues forward to step 1120, where the processor initiates the offline mode of the music service application. From step 1120, the method continues to step 1122, where playback of the playlist stored in the memory of the device is enabled. For example, at step 1122, the offline version of the music service application may be presented to the user with an option to play the automatically-generated playlist (e.g., as shown in FIG. 6 ).
